The injection pump was loose because he tried removing it before selling the core to you. Those three bolts are actually studs - the pump is held on by nuts on those studs which doesn't require access to the geartrain side of the pump. What the PO didn't account for was having to take the drive nut off the front of the pump and likely gave up, leaving the pump loose like that.

[@jeffclark2725]

Thats exactly what happened... thevaccuum pump needed to be removed to take the bolt off to allow the fuel pump to be pulled out... three nuts and washers were on that thing holding it in... that is just like the GM 4.3L, 5.7L, 6.2L, 6.5L in how the fuel pump mounted.. thats how he broke the chain guide...

Hey Eric. I'm a parts guy at a Nissan dealership but I've never even seen one of these come in, so this video was quite a treat. We actually wont even work on these trucks as our lifts REALLY struggle with them. They can weigh over 7,000 pounds.

The 5.0 Cummins V8 that comes out of the XD Titan is ~ $20,000 for a new long block. I hear these engines are struggling with failures at relatively low miles (for a diesel plant) despite its legendary origins.

[@TestECull]

40:06 It's probably torsional vibration. You see this with the Ford 300 I6. That thing is FUCKING INDESTRUCTIBLE, and the stock crank is more than happy to spit out over a thousand horsepower if enough snails are hung off the side. But if you rev it much past 6500 that 3 foot long crank just vibrates itself clean in two. Starts resonating like a guitar string and POING!. Straight six Cummins diesels in Ram trucks are known to do this when revved much past the factory redline as well. Fix is the same in both applications: Fit a harmonic balancer that is capable of changing the resonance so the crank doesn't explode itself. It's also why those straight eights you see in cars from the 1930s, 40s, early 50s rarely revved much past 3,000RPM. The cranks were so long that they would start resonating, snap themselves in half. V8s tend to be much more resistant to this failure mode because their cranks are much shorter(And thus resonate at much higher frequencies), but given this engine was 'tuned' it's entirely possible that it simply revved high enough to vibrate the crank apart. Where this crank failed also lends credence to this. A crank that fails due to excessive torque on it is usually going to shear the snout or the flexplate flange off, depending on which end was connected to the overload. A crank that fails due to harmonic resonance tends to fail right there where it necks down into a journal somewhere. My best guess for this engine's cause of death is operator error. Excessive RPM due to the operator deleting/raising the rev limiter and pushing the engine too hard without making the appropriate modifications to support that higher redline.

[@mikebaz7843]

Nissan TD42 engines snap crankshafts semi-regularly near #6 too

[@r0ck_ste4dy83]

@C6 Modellsport I bought my XD with 27k miles on it. Happened to noticed the harmonic balancer/dampener had a slight "wobble" while running. It wasn't loose, just wasn't running completely true. Replaced it somewhere in the first 3k miles I owned it and I check it every so often. So far the replacement runs true. There was some speculation in the XD community that a poor design of the dampener/balancer contributed to the crankshaft failures. An aftermarket company was even willing to develop one if they had enough pre-orders but it never happened. Most felt the price was too high for a 'maybe'.

[@dougberry2815]

As a former Master Nissan tech, seeing broken crankshafts were extremely common on these 5.0's, especially the 2016 MY. The crank had a weak design, and they would break in the area in the video. If they were kept stock and not juiced up, they generally were ok. Lots of farmers in my area bought the Titan Diesels and expected Chev/Dodge/Ford diesel power out of these engines, but they weren't intended for that kind of work.

Former Titan XD diesel owner here. I bought my 2018 Titan XD midnight edition new in September of 2018. Had 190 miles on it at delivery. It was an absolute amazing truck and handled every load I put behind it amazingly. In January of 2022 it started to sound different, like a knock rather than a clatter that a diesel typically has. This was at 47,000 miles. I took it to Nissan numerous times and told them something wasn’t right. They had corporate specialists come in and look at the truck and I was told numerous times it was fine. In May of 2022, with my fully loaded 8.5x20 enclosed trailer attached, the crank snapped at 55,000 miles. It was violent. Nissan replaced the engine at no cost to me. Total bill was over $22k! I sold the truck to Carmax 7 days after getting it back. Really miss the truck, but to much of a risk when using it at a commercial vehicle.

Had the same truck. Biggest mistake I've ever made. Left me on the side of the road 4 times for EGR, DEF, turbo and fuel pump failures.

I think this really helped the performance of my truck without overkill. I also got a letter yesterday from Nissan, they are giving extended warranties on the Turbo Actuator and the Turbocharger for 10 years or 150,000 miles from the manufactured build date. Plus if you had them replace you might be eligible for full reimbursement, if you own a Titan you should have the letter or get it soon.

I noticed that high pressure pump didn't have threaded mount holes. Those bolts you removed from the front were likely just the mounting studs for it. It probably had nuts on them from the back side of the pump. Someone probably tried to remove the pump and keep it when they realized it wasn't so simple to remove and they just left it in the halfway pried out position you found it in.

[@engnerdan]

I was thinking it was a manufacturing problem with the pump. The holes were never tapped. I would assume they were using a thread forming (forging) tap instead of a thread cutting tap. The hole would be drilled much larger than it would be for a thread cutting operation, large enough that with an impact you could get the bolts to start threading a bit into the unthreaded holes.

I think the original thought of "nuts behind the pump" is correct. Thread forming taps do require a larger tap drill, but never larger than the major diameter (or even close to it, really) of the fastener. If it were tap drilled that large, the tap wouldn't even contact anything to even attempt to form threads. I think nuts were removed from behind the pump.

When he finally did... the plant mechanic guy (Mike) found out Cherokee had stored the engine just bare in the weather *without plugs*. Mike took the heads off and cleaned it all up with sandpaper and whatever else he had in that field, put it back together, installed it and the thing ran like butter. Some people are just magic.

Bad harmonic balancer once, someone mismatched bob weights by 2lb other time! Still went 200+hrs in the field broken!

I knew what you were in for the minute the HPFP pissed out water and fuel on the bench. FWIW broken cranks can be surprisingly quiet on gassers, I snapped one on a Ford with a stick, drove it for months, thought it was the clutch because I could feel it in the pedal. Changed the clutch, no difference, didn’t figure it out for another month when I was in a hurry one day and wound it up and it snapped in a second place on the other side of the rod journal, freeing the rod and allowing the crank snout to flop around and the timing belt jumped and it stopped running. Did a 6.2/6.5 GM diesel once, snapped diagonally inside the rear main cap, sounded like loose torque converter bolts.

I personally drove that truck during the diag process and if you were not listening for it you would never know that is how quite it was. I couldn't believe it when I tore it down the crank came out in 2 pieces just like yours just did however it was a clean break right in the center journal. it was like 4 of the cylinders were running separate of the other 4 but it was such a clean break that the 2 pieces were still in contact rotating together.

Glad you and the family are feeling better Eric!! Your fans certainly missed you last Saturday. I drove a 2017 Titan XD diesel 4x4 crew cab for just over three years for work. At 79,000 miles it went into limp mode one morning on the way to work. After nursing it a couple of miles to the Nissan dealership and dropping it off, we found out 3 days later that the actuator that drives the hybrid-compound turbo variable geometry had failed. It took four weeks to get one because they were failing at an alarming rate. I naturally did some digging on KZbin and came across a video where the same thing happened to another guy - but his failed at about 40k, I believe. When he pulled all the piping, the turbos, and the actuator off the engine, he found that it was so badly coked up, that they had to scrub it with gasoline to get it clean. Come to find out, this had been happening all over America with this engine and Nissan was trying to ignore it. I sent the link to the video to my service guy at Nissan and asked him to please pull all of the turbo piping and the turbos to inspect and clean them. He said “No” because Nissan wouldn’t pay for that under warranty, only to R&R the bad actuator. I asked him if he had watched the video, and he said he did. I asked him if he had kicked it upstairs and he said he did. I asked him what the response was and he said they wouldn’t comment on it and to replace the bad part. Four weeks after the truck went to the dealership, we got it back. 8 weeks after we got the truck back, we sold it before the warranty was out. The same thing happened to the other Nissan XD diesel in the company fleet. Same scenario: about 4-5 weeks to get the part, and we sold the truck about a month after we got it back. It’s too bad. That could have been a great truck. Unfortunately, Nissan had to monkey with the engine instead of just buying it from Cummins. It was overpriced, barely had more towing capacity than the 5.6 gas engine, and the transmission totally sucked. The truck was quiet, rode nice, and got pretty good mpg’s for what it was.

They failed miserably. They had a chance too, as a lower cost fullsize truck diesel option would have sold if it was good.

Then the bolts were forced down tight anyway through the cross threading. It would be like trying to pull the pump in with one bolt all the way in one shot, instead of tightening the 3 evenly to pull it in.

When I got it home I pulled the engine and found that there was a crack most of the way across one of the crank throws. Each time the torque reversed, the crack would open and then snap back together making the knocking sound. Good thing I didn’t drive it further since in the original Mini the gear box was in the oil sump right below the crank and dropping pieces into it would have locked up the wheels!

Eric, a great teardown as usual. You have people at your shop, I suggest you remove the casters from an engine stand and weld it to a nice heavy piece of steel. Weld a few loops for forklift tines to move around the shop. It would make teardowns so much easier not to have to chase the engine stand all over the place!

Some diesel engines do have pistons that come out of the deck about as much as the thickness of the head gasket, makes for more or less zero piston to head clearance for maximum compression. But also no room for mistakes, pretty easy to smash some valves that way.

My first car was a hand me down FIAT that my brother (brilliant man with absolutely no mechanical aptitude) ran overheated and low on oil for quite a long distance. Shortly after being blessed as it's second owner, the crankshaft broke at freeway speed (yes, 70 mph) destroying virtually every internal engine component. I should mention that a suddenly seized engine in a manual transmission car can make them a handful to control. Anyway, I'm still here to tell of it so while the engine was a total loss, there was a bright side. Thanks for this and all your videos. Keep up the good work!

15:31 Torque spec for the cylinder heads is 30 lb-ft, then 89 lb-ft, then another 180 degree turn. I'm in parts at a Nissan dealer, and we've had a couple diesel Titan's in that have gotten the engine replaced. I can't remember exactly what they were for, but we've done them. According the Nissan's parts catalog, the new engine is supposed to come with the turbos, exhaust and intake piping, and fuel lines, but both we have ordered have come in without everything, which was just wonderful for the tech on the first one he did, especially since the warranty labor time didn't include having to swap everything over.

[@rotax636nut5]

A friend brought me a broken crank from a 2 cylinder compressor, he'd tried to get a spare crank but couldn't and was too tight fisted to buy a new complete pump, I had a look at the break and it was like a 'cracked' connecting rod, the break fitted back together perfectly after I'd filed a few burrs off it, I formed a plan to repair it and started by epoxying the 2 parts back together and clamping the crank in a bench vise so the 2 parts were tightly knitted together under pressure, then after a day or so for the glue to harden I put the crank up in my mill and drilled and tapped holes from the outside through the web to and through the break line, the holes were clearance on the outside of the crack and tapped 5/16 UNF at the bottom with the break line between the clearance hole and the tapped hole. I managed to get 3 tapped holes and counterbored the tops for the cap head 5/16 bolts installed to firmly bolt the 2 pieces back together, the epoxy was just to hold the 2 parts accurately together while I drilled and tapped the holes, the glue never let go and held the 2 parts of the crank together until the cap bolts were installed and tightly Loctited in place. I checked the crank in my lathe for straightness and it was acceptable at less than 0.002" out and it spun freely in the pump housing. My friend took everything away and re-assembled the pump back at his shop and got it working which it did seemingly normally and after a year of continuous use in his shop it was still working perfectly, so there you go, how to repair a broken crank (compressor)

I own one of these and seeing the insides is a treat. The 5.0 is almost indestructible if taken care of and and not abused, mine has 100k on it and runs smoother than new. Oil analysis shows no wear concerns yet. The tranny attached make the combo surprisingly beefy, overbuilt. I understand folks who question the 5/8s size and 6 lug hubs… I feel Nissan missed a LOT of sales not getting closer to what the other 3/4 tons can do.

On the high pressure pump, did Cummins use the wrong bolts with the wrong thread pitch when assembling the engine, or did someone have it apart. There is no way there should be a gap that big if everything is tight. Only at 13:30 now. Maybe there is an answer later in the video.

That pretty blue crank remnant will make a nice desk ornament 😄 That engine looked very clean inside for a diesel with over 100K on it.

I had a 89 BMW M3 in my shop years ago and the guy had a misfire for a long time. Was a bad wire inside the injector harness, got it fixed and got him back up and running good. He went out for a track day and within 2 laps snapped the crank clean at the journal very similar to your titan xd engine. Although the driver of the car shut it down immediately. We where able to replace the crank, clean up the rods, similar minor damage as seen in your engine as well. We upgraded the cams, tuned the ECU and he was back out at the track having a blast. Maybe the culprit in you titan engine can be traced back to that injection pump and perhaps creating some kind of fuel injection related misfire that stressed the crank harmonics and snapped it.

[@whalley6044]

To me it looks like a fatigue crack that started at the journal radius. If you still have the crank you might look closely at the other side of the broken journal and other journals. It's normal for multiple fatigue cracks to start then one grows to failure.

[@F14thunderhawk]

its a fatigue crack that got a bit of help from a bad cooling layout and one miracle of a void in the manufacturing process. Theres a bubble in the exact center of that break, inside the machined faces of the crank shaft that isnt polished by wear or machine tools Thats a hell of a manufacturing defect

[@josephbrabenderiii2049]

From 40 years of designing to prevent fatigue failures, I agree. But...there is no excuse as the mechanisms are pretty well understood as is the design methods to prevent. If I were to venture a guess...a six cylinder design that was extended to eight and deficiencies got the "good enough" stamp. "Safety factors in original design will be adequate". Unfortunately (if true), the failure began from the day the engine was first put under load

Classic fatigue failure, started from the inside of the crankpin where meets the web which is typically the highest stress area. Possibly the fillet radius wasn't sufficiently large or was incorrectly formed during manufacture.

[@Bacongrease00]

Diesels have piston protrusion above the deck up to .035”. The head gasket is usually .050-.060” so that gives you the clearance. Much different than your gas engines. The combustion chamber is in the piston which is why it looks like a bowl because it is.

[@tommuborgir7747]

If you cant find a ball hone, get a brass or steel pipe (tube) brush, get a roll of scotch-brite, fold it over and wrap it around the brush. Use some rubber bands to keep it from coming apart, then just put it in a drill! I use this method to clean various holes and bores all the time

Diesel pistons often protrude slightly above the deck, and the headgaskets have selectable thicknesses to accommodate and maintain the high compression ratio. The swollen piston that touched the head is usually caused by a leaking injector that heats and swells the pistons, more ofter leaking injectors burn holes in the piston where the injector nozzles spray

Look at the ECM harness. Guarantee you’ll see on cylinder 7 & 8 injector harness wire fraying. It’s been found that the tight tension from zip ties cause fraying on the wiring. Eventually the motor will be out of timing and hydro locking it. That’s why it was blueing the metal from over heating. Everything was out of sink. Melted the bearings and cracking the crank shaft.
